recently my NR often fails to put news threads together. Is it just my NR
or is there still something wrong with the News ↔ Mail gateway?
Probably a problem with the gateway
See the newline after Message-Id: and In-Reply-To:

Right. The format is valid but presents an edge case.
<From RFC 2822 - Internet Message Format (RFC2822) >
2.1.1. Line Length Limits
Each line of characters MUST be no more than 998 characters,
and SHOULD be no more than 78 characters, excluding the CRLF.
</>
Message id’s can be long and can’t wrap, so the mail agent raising
the problem has given the best possible chance of avoiding a
“disastrous wrap” by starting with a CRLF.
Meanwhile everyone else’s mail/news agents are flouting the
recommendations by sending lines of more than 78 characters
without a care in the world.
IMHO they’re lucky that email isn’t transmitted on punch cards.
